In the process that the auxiliary spline shaft 81 drives the fixed plate 74, the supporting rod 73 and the bottom plug 71 to move downwards, the auxiliary spline shaft 81 rotates rapidly along with the inserting rod 41, the auxiliary spline shaft 81 drives the blades 82 to stir in cooling liquid to form a vortex which flows downwards, when the fixed plate 74 passes through the first side groove 61 downwards, the first L-shaped through hole 711 is communicated with the lower pipeline of the L-shaped waste liquid pipe 6, cooling liquid flows through the L-shaped waste liquid pipe 6 to be discharged into external waste liquid recovery equipment, meanwhile, the external cooling liquid conveying equipment supplements cooling liquid to the cooling tank 9 in time, the cooling liquid level in the cooling tank 9 is ensured to always keep overflowing the liquid supplementing pipe 91, the phenomenon that the gear is soaked in the cooling liquid instantly is realized, quenching oil remained on the outer surface of the gear is rapidly leached out into the cooling liquid, the quenching oil directly flows downwards from the first side groove 61 along with the cooling liquid, the cooling liquid is prevented from being accumulated at the bottom of the gear for a long time, the second L-shaped through hole 741 of the fixed plate 74 leaves the first side groove 61, when the second L-shaped through hole 741 of the fixed plate 74 is communicated with the second side groove 62, the cooling liquid is completely leaves the L-shaped waste liquid 6, the electric liquid flowing downwards through the lower pipeline of the L-shaped waste liquid pipe 741 is completely, the cooling liquid is required to flow through the second side groove 741 is stopped, and the cooling liquid can flow through the bottom of the gear is more than the cooling liquid is more effectively improved, and the cooling liquid can flow through the bottom through the gear is more than the cooling liquid through the gear through hole through the L-hole.
Example 2
In this embodiment, as shown in fig. 1-11, a ring of baffle ring 54 is bolted to the bottom of the quenching chamber 5, and a plurality of sealing structures adapted to the structure of the second L-shaped through hole 741 are disposed on the inner surface of the baffle ring 54, wherein the sealing structures are protrusions made of elastic materials, and edges of the protrusions are inclined surfaces, so as to facilitate pressing into and withdrawing from the openings of the second L-shaped through hole 741.
The multi-shaft manipulator 21 drives the gear to be drawn out from the high-frequency induction heater 10 through the clamping mechanism and then transferred to the upper part of the fixed plate 74, the fixed plate 74 is inserted into the bottom of the quenching cabin 5, the baffle ring 54 covers the outer surface of the second L-shaped through hole 741, the adjacent second L-shaped through hole 741 is blocked by the sealing structure of the baffle ring 54, the bottom of the quenching cabin 5 is isolated by the fixed plate 74 instead of shielding gas, the outside air is prevented from entering the quenching cabin 5, the shielding gas in the quenching cabin 5 can only be discharged from the upper part, a small amount of quenching oil doped in the shielding gas can only be discharged from the upper part of the quenching cabin 5, and the phenomenon that the cooling liquid and the quenching oil are mixed is reduced because a small amount of quenching oil doped in the shielding gas is directly sprayed downwards into the cooling liquid of the cooling pool 9 in the primary cooling treatment work of the gear is avoided.
Then, the telescopic end of the electric push rod 33 pushes the vertical sliding block 32 to move downwards along the mounting cylinder 31, the vertical sliding block 32 drives the inserting rod 41 to be inserted into the lower auxiliary spline shaft 81 through the spline groove 411, and pushes the auxiliary spline shaft 81 to drive the fixing plate 74, the support rod 73 and the bottom plug 71 to move downwards, meanwhile, the fixing plate 74 leaves the baffle ring 54 downwards, the second L-shaped through hole 741 leaks out of the baffle ring 54, and the gear is completely cooled by cooling liquid.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
